FOUNTAIN PEN original appiication inea .T iinefas, 19V24,jseiia1l No. 722,493. Divided This application-isa division' ofvmy origi-I nal application Serial No. 722,493, filed J une 26th, 1924, for fountain pens and reillable pencils. Y

The present invention relates to fountain` for allowing thequick and easy lling of the showing the ink sack in its normal or eX-4 2ov pen.

The various objects of my invention will be -clear from thedescription which follows, and from vthe drawing, in which,

Fig. l is a sectional view of a combination writing device including a fountain pen and pencil, theink sack for the pen being shown compressed. r

Fig. 2 is a longitudinal section thereof,

tended position.

Fig. 3 is a cross-sectional View, taken on the'V line 3 3 of Fig. 2, showing by means of theshading, the shape of one of the cam surfaces,

the overlying part being removed for that purpose.

Fig. 4 is a similar view, taken on the line 4-4 of Fig. 2, showing the annular walls in the cap forthe reception of leads.

v)In that practical embodiment of my inven" usual description, if desired, ina mannerl whi'chwill be obvious to those skilled in the art and hence, which need not be `descrbiedV or shown.

My improved 'pen includes an -outer shell or barrel which is preferablythough not necessarily, formedk integrally vwith a. peniV holding or terminal portion or head pie/cell,"

adapted to removably receive the feeder 12 and the pen point 13.

Extending longitudinally through the barrel and attached to the feeder 1 2 as by means of a slip section 35, is a rubberink sack 14 of the usual type. Said sack v'is adapted to be compressed todrive the vairl out therefrom wherebya new supplyof ink is sucked into and, this app1ication vfiled Decemberl 1 1, 1929, serial N. 413,347; A

thesaclwhen it returns automatically to its normal shape. The Vcompressing meansffor. the sack includesa plateV or leaf spring 15, one-endofwhich is bent and fixed relatively to thebarrel as at 16 being 4inserted into'the recess 34 between the slip section35 yand the barrel 10. The other end ofthe spring attached as at 17 to a longitudinally displace`` able member 18, whereby one end 'only of the plate spring 15 may be moved longitudinally to bow the spring and thereby to compress the sack 1 4. Said member 18A engages the end 17 of the plate spring 15 so that lonf gitudinal lmovement of the member 18 causes similar'movement of the end 17 and thereby bows the spring. Said member ,18, is mov- `ablyitted in the end. of thebarrel opposite i that Aof the head piecl p y 11,and is arranged for operation bya cooperatingcam;

Toward fthisend, the inner faceofthe 'i member 1 8 is formedor associated with cam surfaces 19 whichengage corresponding cam surfaces 20 associated with A the rotatable member 21. To `maintain the member .21 against longitudinal movement in the barrel, an annular groove as 22 is formed therein,

cof

suitablel pinsj as 23 projectingfrom the barrel, being inserted into 'said groove andthereby allowing Vrotation only of theimember 21.

Part of said member *mayfproject from the'l barrel and the' projecting vpartmay-fbe serff rated as at V24 to `providea` roughened surface adapted to be conveniently grippedby the operator for theproper manipulation thereof;`

If desired, the member'21. may be continued in the form of a tapered casing 25 for forml ing thev pencil partof my device and for the receptioni of a suitable lead feeding or sup.- porting mechanism and sleevev 26,though it will be understood that where my'invention isto be .applied only tol kfountain pens, the mechanism 26 may be omitted as well as thev .tapered portion 25 and the member 21 `may be terminated at or about the line 27. Byturning the member 2l, the inner member 18 is-moved inwardly'orv outwardly as shown in Fig. 1, thereby compressing or flattening the spring 15, asthe result o'flwhichv .ico

i' the sack will 'beiactuated to draw'ineor discharge ink` as the case maybe.

The cap Vof the pen may comprise two sections, an elongated tubular section 28 and a shallow-discdike capping section 29. An annular chamber as 30 may be formed interiorly ofthe cap l28 for the reception of leads 31 or other materialg'while the sectionV 29 is Y It-willbe understood-th v vsliownaiid vdescribed a specific embodimentk f y ofjmy invention, 'I do. vnot intend to limit' that a cam member is providedfat the other end. ffBe`cause of `this straight,construction,
